The specific embodiment
Instance one:
Certain ore deposit mine tailing unit weight is less, and porosity is relatively large, and-320 order content are 45.45%, belong to fine tailings.Adopt this device to carry out simulated experiment, the result shows that when rotating speed was 0.05r/min-0.8r/min, the limting concentration scope was 67.41%-70.73%, can think that this concentration range is this mine tailing lotion concentration.Under the different rotating speeds, when mixing time reached 12h, slurry level no longer changed, and the concentration that reaches capacity can think that this mine tailing concentration when the densification time is 12h no longer improves, and suggestion deep wimble thickener design residence time of material is 12h.And this mine tailing to adopt indoor amount to carry out the limting concentration that obtains of the static sedimentation of tube be 55.82%.It is thus clear that, rely on the limting concentration of static sedimentation device prediction mine tailing also unreliable, can not obtain the Cmax value that this mine tailing prepares lotion.
Instance two:
Certain ore deposit mine tailing-200 order reaches 35%, and granularity is thicker relatively.Main mine tailing lotion concentration, dense time and the suggestion deep wimble thickener ratio of height to diameter investigated of test.It is 4 groups that content of the test is divided into, and conceptual design increases progressively the mud layer height change process that realizes according to being that the mud layer height is different according to every group of experiment mine tailing addition successively.Mine tailing adds mass fraction and is followed successively by 11%, 25%, 40%, 50%, and the addition of water is all identical.4 groups of experiment flocculant ton consumptions (15g/t), flocculant concentrations (0.3%), rotating speed (0.1r/min) are all identical.Result of the test shows, when the mud layer altitude range was 31mm～200mm, the limting concentration scope was 73.26%～78.30%; And mud layer is high more, and densification concentration is big more, and along with the continuous increase of densification time; The speed that concentration increases reduces gradually, and suggestion lotion concentration is about 76%.Through calculating the corresponding ratio of height to diameter scope of limting concentration scope is 0.31～2, and regression analysis obtains being parabolic relation between limting concentration and the ratio of height to diameter, and with 76% substitution of lotion concentration, obtaining the ratio of height to diameter value is 1, and the suggestion ratio of height to diameter gets 1.Under the different sludge layer height, the slip time of staying, underflow density basically no longer changed when reaching 6h, when the time of staying reaches 9h, and the slip concentration that reaches capacity.Therefore, the suggestion material is 9h in the deep wimble thickener internal stops time, can reach abundant densification.
